LEON'IBENOIT, OF CHICAGO, ILLINOIS 4 LInoR CLOSURE Application filed. December 30, 1929. Serial No. 417,309.

g This invention relates to lids or closures. of a type which are suitable for hermetically sealing containers in which foodstuffs or other commodities may be placed. The present :improvements will be described in connection" with: closuresof conventional type employed with'glass contain-,,

ers, such as jelly glasses and the like. It will be understood that the invention is not intended to be limited to this particular closure since it may be applied to any kind of closures which'are normally stacked together for ease in handling. In practice such closures are'closely nested and tend to adhere together, and difliculty is frequently encountered in separating them in the operation of applying the closures to their several containers.

It isa primary'object of my invention to provide a method of stacking such closures so that adherence between them is positivelyprevented. The invention also comprises the resulting stack. 7

My invention further resides in the combination, construction and arrangements of parts illustrated in the accompanying drawing, and while I .have shown herein a prefferred embodiment,'I wish the same to be understood as illustrative only and not limiting the scope of my invention.

In the drawing, Y V Figure 1 is a sectional viewthrough two adjacent, but separated, closuresto which my invention may be applied, 1 Fig. 2 is an elevation of one of the closures of Fig. 1 as seen from the underside,

Fig. 3 is a sectional view through a stack of closures of the forms shown in Fig. 1, and r Fig. 4 is a similar view of a stack made up from three modifications of the closures.

Referring to Figs 1 to?) of the drawing,

a series of closures 10 areformed: from flat blanks which are pressed to provide channels 11 around their edges which commonly are turned to provide flanges, as shown, The e blank walls bordering these channels are commonly slanted or inclined to an extent which permits adjacent closures to nest in inter-f fitting relation. These channels adherently receive a flexible sealing, gasket 12 which is usually of rubber or rubberlike material.

which tends to 'befta'cky particularly when new. It is the ordinaryi'commercial practice to stack a large number of exactly similar closures such as lOI't'ogether, with the result that"the'exteriorsurfaces of "the channels 11 come into contact with the tacky surfaces of the gaskets 12. of the superimposed clo-, sures so that the closures frequently adhere together and require to be separated by hand before they can be used. This adherence is very objectionable, particularly where auto-' matic machinery is employed for.;applying closures to containers;

In order to obviate this difficulty I provide a second series of closures 10, which are similarito the closures 10. The closures 10 are provided with annular ribs 18 which are pressed up from their inner portions within the channels 11. The closures 10 are provided with similar ribs 13', which are of different diameter from the annular ribs 13. As shown in Fig. 3, I- produce astack of closures by superimposing, alternately, closures 10 and 10 until a stack of thedesired number is obtained. As will readily be seen in Fig. 3 the ribs 13 and 13 are unable to come into registry so that they serve asspacing projections which prevent close contact between adjacent closures which might re- 7 sult in their adherence together.

It will be understood thatmyinvention may be modified in many ways. Thus, as

shown in Fig. 4, I may employ threev series of closures 14, 14: and 14 which are similar ex+ cept that they are provided with up-pressed annular ribs 15, 15 and 15 which are of different diameters- These closures .may be stacked regularly or irregularly, provided that each closure ofone series is not in juxtaposition to another closure of the same series. Obviously a greater number of series may be employed if desired.

It will be'understood thatthe spacing projections are not necessarily of annular form. They may be constituted by other figures,

ornamentation, trade-marks, or the like, pro- 7 vided that such figures or the like on any closure cannot be brought into register with the V deformations in the adjacent closures.

I claim:

1. A stack of closures comprising closures of a plurality of series in alternate relationship, each closure of a series being superposed and in juxta-position to a closure of adifferent series, all the closures being provided with annular ribs spaced from the edges thereof, thediameter of the ribs being different in the closures of each series, whereby nesting of adjacent closures is prevented.

2. A stack of closures comprising closures of aplurality of series in alternate relationship, each closure of a series being superposed and in juxta-position to a closure of a different series, all the closures being provided with ribs spaced inwardly from the edges thereof, thearrangement of the ribs being different in the closures of each series, whereby nesting of adjacent closures is prevented.

In testimony whereof, I have hereunto set my hand this 26th day of December, 1929.
